As a Senator he had nothing to do with the House Un-American Activities Committee which investigated private citizens such as Hollywood actors and producers etc.
Hello, TigersEye. I was making a (misguided) attempt at being dismissive...but your correction was needed and is appreciated.
“The portrayal of Senator Joe McCarthy as a wild-eyed demagogue destroying innocent lives is sheer liberal hobgoblinism. Liberals weren’t cowering in fear during the McCarthy era. They were systematically undermining the nation’s ability to defend itself while waging a bellicose campaign of lies to blacken McCarthy’s name.
Everything you think you know about McCarthy is a hegemonic lie. Liberals denounced McCarthy because they were afraid of getting caught, so they fought back like animals to hide their own collaboration with a regime as evil as the Nazis.”
